About G13
G13 is more than just a cannabis strain; it is a true icon with a story that seems to come straight out of a spy film. The legends surrounding its origin are countless, but the most well-known is that it was developed in a secret government laboratory of the United States government. Some believe the name stands for "Government Indica Strain #1" , while others think that the "G" stands for Government and "13" for the 13th letter of the alphabet, "M" (for Marijuana) . This story has permeated pop culture so deeply that the strain was mentioned in movies such as American Beauty, Half-Baked and Pineapple Express
What we wél with certainty know is that the G13 genetics came into the hands of Nevil Schoenmakers, the founder of the legendary Seed Bank of Holland. According to legend he managed to obtain a cutting or seeds of the G13, probably via Sandy Weinstein, who in turn would have had connections with an unknown researcher. Some claim that this researcher smuggled seeds from the Mississippi laboratory, others speak of a single "bite" (cutting) . Once in the Netherlands the G13 became the basis for countless crosses and spread worldwide.
The officiële state institution University of Mississippi has been cultivating cannabis for research purposes on behalf of the government since 1968. Although there are no public documents confirming the existence of a "G13" strain there, it is plausible that the legend contains a kernel of truth and that an exceptionally good phenotype escaped from this research into the commerële cultivation world.
The buds of G13 are dense and compact, covered with a thick layer of trichomes and striking dark orange hairs – exactly as you would expect from a quality indica.
THC content & Effects
G13 is known for its high potency. The THC content varies, depending on the specific variant and cultivation, from 20% to as much as 32% . This makes it a very powerful strain that is especially suitable for experienced users.
The effects are characteristic of a heavy indica. Users describe the high as a deep, relaxing body stone that builds up slowly and can last for hours . An experienced user describes it as: "You feel as if you are drunk, but without being functionally impaired, it's just the mental state you are in. The primary state is also super trippy and feels like you are in a dream" . Another calls it "a light out-of-body experience where you still have control, as if you are watching your own life and steering your body from a few centimeters away" .
After the initial euphoric headrush, an overwhelming physical relaxation follows that quickly makes you end up on the couch. This makes G13 perfect for evening use, but less suitable for moments when you still need to be active.
Aroma & Flavor Profile
The aroma of G13 is classic and unmistakable. The scent is described as an earthy, sweet and woody mix with subtle spicy and pine notes. It is a strong, penetrating scent characteristic of high‑quality indica strains.
When consuming, the flavor fully comes through:
Inhalation: Earthy and sweet with notes of pine and herbs
Exhale: Subtle citrus and pepper, with a long-lasting earthy finish
The flavor is "classic in aroma and taste", exactly as a seasoned old-school indica cannabis enthusiast would expect .
Terpene Profile
Caryophyllene (dominant): Responsible for the spicy, peppery undertone. This unique terpene can bind directly to CB2 receptors and is known for its anti-inflammatory and pain-relieving properties.
Limonene (dominant): Provides fresh citrus and sweet notes. This terpene is known for its mood‑enhancing, antidepressant and stress‑relieving properties .
Myrcene (dominant): Adds an earthy, spicy depth and enhances the relaxing, calming effects of the strain.
Linalool (supporting): This floral terpene, also found in lavender, contributes to the calming, relaxing and anxiety-reducing properties of the strain.
This synergistic combination of terpenes provides the classic indica profile and the deep relaxation that G13 is so famous for.
Who Is G13 Perfect For?
G13 is the ideal choice for the experienced user who is looking for a powerful, legendary indica with a rich history. It is perfect for moments when you want to fully relax and let all the day's stress melt away.
Ideal for:
Chronic pain, insomnia, stress relief, anxiety, depression, evening relaxation, quiet evenings at home .
Note: Due to its high THC content, G13 can cause dry mouth, dry eyes, dizziness, or, in rare cases, panic reactions .

A user warns: "I felt my heart tighten and sat down, and thought about which movie I wanted to watch, and then I know, I tell my friend that I am having a panic attack"
